South of the Polar Circle
The Polar Circle is an imaginary line based on the earth’s axial tilt at 66° 33’ 44.8” North and South. By definition everything below the southern Polar Circle (i.e. further south) is Antarctica. In the case of the Antarctic Peninsula ships will try to go past the Biscoe Islands, heading for Marguerite Bay. There are very few scientific stations or bases south of the Antarctic Circle as the ice conditions can make it difficult to bring in personnel, material and provisions by ship. Argentina and the UK both maintain permanent stations in Marguerite Bay, while Chile has a summer station at the entrance to the bay. The main attraction here is what makes it so difficult to reach: a land and sea scape covered in snow and ice.
